Now it seems that the nodes are able to talk with each other, but are returning the container IP.

It seems that you the `network.publish_host` is need indeed, but also the `network.host`.

Try to use this in the yaml files:

```auto
  - network.host=0.0.0.0
  - network.publish_host=host-ip-address

```

It seems to have worked on this [simular post](https://discuss.elastic.co/t/which-network-host-to-use-to-connect-nodes-running-inside-docker-containers-on-separate-machines/153204/3).
